It all started with an overnight hospital stay for 3 year old Freddy. When he came home, his bonded brother Flaco showed signs of feline non-recognition aggression, (something I never heard of before). We're currently at 2 months of following a slow re-introduction process. They will eat together twice a day and play in the same room twice a day, mostly separately, for about 15-20 minutes. This stage has been going on for several weeks. If we try a longer play time Freddy will end up stalking Flaco and fur will fly. I do try to distract him with toys and this has only happened twice. Since I don't want play time to end badly I keep it short. The rest of the day they remain separated. I swap them out of their areas daily, too. It doesn't appear to be a scent thing anymore. They also will use each other's litter box which I take is a good sign.
What else can I do to help them along?
